Environmental protection and saving energy

4.1 Saving energy
If you follow these instructions, your appliance will use less energy.
Choose a burner roughly the same size as your pan.
Centre the cookware on the hob.
Tip: Cookware manufacturers often give the upper diameter of the saucepan. It is often larger than the base diameter.

• Unsuitable cookware or incompletely covered cooking zones consume a lot of energy.
  Cover saucepans with suitable lids.

• Cooking without a lid consumes considerably more energy.
  Lift lids as infrequently as possible.

• When you lift the lid, a lot of energy escapes.

Use a glass lid.

• You can see into the pan through a glass lid without having to lift it.
  Use cookware that is suitable for the quantity of food.

• Large items of cookware containing little food need more energy to heat up.
  Cook with only a little water.

• The more water that is contained in the cookware, the more energy is required to heat it up.
  Turn down to a lower power level early on.

• If you use an ongoing power level that is too high, you will waste energy.

4.2 Disposing of packaging
The packaging materials are environmentally compatible and can be recycled.
